ELECTRIC TOASTER.

- Application filed July 16, 1923. serial No. 651,898.

1o allw liom it may concern: Be it known that I, GEORGE E. V. Hrrz- ROTH, a citizen of Canada, residing at Ham-v 1]ton,,1n the Provlnce of Ontario, Dominion.

of Canada, have invented certain new and useful Improvements in Electric Toasters, of which the following is a specification.

This invention relates 'to an electric toaster.

The object of the inventionis to provide an apparatus operable in combination with a toaster whereby to discontinue a toasting operation at a predetermined interval and thus to eliminate the burning of the bread or the like being toasted.

Other objects, and objects relating to details of construction, combination and ar-. rangement of parts will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawings, in wh1ch:--

Figure 1 is a view in side elevation showing a toaster together. with apparatus of the present invention when connected with the toaster,

Figure 2 is a top plan view of the apparatus for stopping a toasting operation,

Figure 3 is a detailed plan view of the revoluble disc employed with the apparatus for stopping a toasting operation and showing the manner in which the disc is held when when toaster is not being utilized.

Referring to the drawings more particularly. the toaster may comprise a base 10 which may be supported by suitable feet or legs 11. The base 1.0 carries the usual core 12 which supports suitable resistance wires not shown. The core 12 is preferably of the shape shown and upon each side thereof there is rotatably supported a rod 13. Each rod 13 carries a frame 14. Also each rod has associated therewith a suitable coil spring 15, whereby to urge the same for swinging the associated frame 14 outwardly and downwardly or in other words to its non-operative position. Also each rod 13 may be provided with a thumb nut 16,

. whereby the same may be manually rotated for swinging'the frames 14 against the tension of the s ring 15.

The electric motor and controlling apparatus of this invent-ion may comprise a frame or casing, generally indicated by the reference numeral 17 which may be supported by suitable legs or feet 18. Within this frame there is supported a disc 19, said disc having a vertical shaft 20 ektcnding therethrough and the lower end of the shaft is supported by a post 21 carried by the frame 17. Also a ball bearing 22 maybe utilized in order to permit easy turning of the disc 19. 'The upper end of the shaft 20 is engaged by a pin 23 carried by the frame 17. T

e frame 17 also supports a magnetic core 24 which -ispreferably U-shaped I as shown, and which carries a pair of electro-magnets 25 which are preferably disposed beneath the disc 19. .This core also carries a third electro-magnet 26 which is disposed above the disc 19.

The frame 17 may further support a connecting plug 28 from which there may be extended the two wires 29 and 30. The wire 30 is extended upwardly through the bottom of the frame or casing 17 and the electromagnets '25 connected in series with this wire. The wire 30 is further extended, as at 31, and connected with one terminal of the resistance wire employed for the toaster. The other terminal of said resistance wire is connected to the wire 29. The electro-magnet 26 is connected in shuntwith magnet 25 by the wire 31 as shown. The plug 28 is adapted to be connected to a socket 32 whereby to supply electric current to the toaster. The arrangement of thecoils 25 and 26 together with the disc 19 is the same as employed in a conventional form of induction meter and, of course. it is to be assumed that alternating current is employed for operating this toaster.

A. rod 33 is fulcrumed by the frame or casing 17, as at 34. said rod having pivotally connected to its upper end. as at 35,

the one end of a rod 36. The rod 36 is supported for longitudinal movement by a suitable guide member 37 and the forward end of the rod 36 is provided with a pair of divergent prongs 38, each prong terminating at its outer end in an extension 39. With the frames 14 swung upwardly to the position shown in Figure 1 the same may be engaged by the prong extensions 39 and with the rod 36 in the position shown in Figure 1 the frame 14 may be maintained against downward swinging movement. The lower end of the rod 33 has pivotally connected therewith, as at 40, a small frame member 41, said frame member being provided at its lower end with a lateral extension 42. The inner side portion of the frame memher 41 rotatably supports a roller 43 which is adapted to engage upon the periphery of the disc'l9. The disc 19 has its periphery provided with a straight edge portion 44 and also the disc 19 carries upon its lower side a pin 45, said pin occurring adjacent and centrally of the straight edge portion 44 as shown to advantage in Figure 3.

In the use of the present apparatus a slice of bread may be placed upon the inner side of each of the frames 14 and then the frames swung upwardly as shown in Figure 1 and the rod 36 moved forwardly so that its prong extensions 39 may engage with the frame 14. Assuming that the wires 29 and 30 have been connected to a suitable source of electric current supply whereby to supply current to the resistance coil of the toaster and also to the electro-magnets 25 and 26, then the tendency of the disc 19 will be to rotate in a counter clock-wise direction. With the forward movement of the rod 36 the extension 42 carried by frame 41 will bedisengaged from the pin 45 carried by the disc 19, whereby to permit rotation of the disc 19 under the influence of the electro-magnets 25 and 24. During the interval the rod 36 is moved forwardly to engage with the toaster frame 14 the disc 19 will revolve a sufficient distance so that the longitudinal center of the straight edge 44 of said disc is brought out of register with the roller 43. Upon releasing the rod 36, that is after the same has been properly engaged with the framemember 14, the roller 43 will engage upon the periphery of the disc 19 and hold the rod 36 against rearward longitudinal movement. Upon the disc 19 completing substantially one rotative movement the roller 43 will move upon the straight edge 44 of said disc and the weight of this roller together with the frame 41 will swing the lower end of the rod 33 in wardly to a point where the roller will engage the straight edge 44. Upon the roller 43 assuming substantially the position shown in Figure 3 the rod 36 will be drawn rearwardly a sufficient distance to release the frames 14 of the toaster and permit said frames to swing downwardly under the tension of the springs 15. It will'be assumed that the time necessary for the disc 19 to make one complete revolution is sufficient to toast one side of the bread carried by the toaster frames 14. The bread may now be turned over on the frames 14 andthe frames 14 raised and engaged by the prong extension 39 of the rod 36. With this forward movement of the rod 36 the pin 45 of the disc 19 will again be released and the disc 19 revolved to perform the same operation heretofore described.

While I have shown and described the preferred form of my invention, I wish it to be understood that I am aware of the fact that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from the spirit of the invention, as indicated by the appended claims.

I claim:

1. In combination, an induction motor, including a stationary field and a rotor, a toaster connected in series with the field of saidinduction motor, and means whereby an object being toasted may be moved out of toasting relation with said toaster by the action of said rotor at a predetermined moment.

2. In combination, an electric toaster, a rotatable element connected in the electrical circuit of the toaster and adapted to be propelled by current flowing through the toaster, and means whereby an object being toasted may be moved out of toasting relation with said toaster by the action of said rotatable element at a predetermined moment.

3. In combination, an electric toaster, and means actuated by current flowing through the toaster whereby anobject being toasted may be moved out of toasting relation with said toaster at a predetermined moment.

4. In combination, a toaster, a plurality of frames carried by the toaster adapted for outward swinging movement, a rod adapted for longitudinal movement, means carried by the rod adapted to engage the frames of the toaster and hold the same in operative position, an electric motor connected in the electrical circuit of said toaster, said motor including a rotatable disc, and means whereby the rod will be moved. for releasing said frame of the toaster upon each complete rotation of the disc.
